Editor’s Note: From time to time the Katusa Research Special Situations team looks deep into different sectors. Over the next three days, we’ll introduce you to a monster profit generating machine and the company leading the charge.

You’ve probably never heard of the seventh-largest company in the world.

The top six – Apple, Google, Microsoft, Amazon, Berkshire Hathaway and Facebook – are household names. But the current seventh-largest company didn’t even rank in the top 10 in 2017.

But it owns a social media network actively used by 15% of the world’s population.

It owns the leading online video streaming platform in China.

It owns the largest online library in China.

It owns the top three music streaming services in China.

It owns the Chinese equivalent of Google Ads.

The list goes on. But the fifth-largest company in the world – Tencent – is a video game company.
